error[E0599]: the function or associated item `make_g` exists for fn pointer `fn(&())`, but its trait bounds were not satisfied
--> $DIR/issue-57362-2.rs:22:25
|
LL | let x = <fn (&())>::make_g();
| ^^^^^^ function or associated item cannot be called on `fn(&())` due to unsatisfied trait bounds
|
= note: the following trait bounds were not satisfied:
`for<'a> fn(&'a ()): X`
= help: items from traits can only be used if the trait is implemented and in scope
note: `X` defines an item `make_g`, perhaps you need to implement it
--> $DIR/issue-57362-2.rs:8:1

LL | trait X {
| ^^^^^^^
error: aborting due to previous error
